Spin-dependent decays of theΛc

Abstract

A formalism for analyzing spin correlations in multibody decays of ${\Lambda }_c$ is presented. It is a generalization of the $\alpha$, $\beta$, $\gamma$ formalism used to two-body hyperon decays. Application to semileptonic ${\Lambda }_c$ decays and to a few nonleptonic decays are also discussed.
